A couple of TLDs will probably become hot properties, and most will not. Those that become hot may include some that have been around for a while, like .us and .info. Most sheep know as much about those two as they know about any of the new gTLDs, so any alternative to .com/.net/.org stands a better chance of becoming popular. Such a gamble, but there will probably be a couple of winners somewhere in the mix. In fact, with the current "pre-registration" hype, anyone trying for an alternative name now will only find that .us, .info, .biz, .mobi, etc. are actually available now and functional.
